What are the basic trig identities? sin x = 1/csc x csc x = 1/sin x cos x = 1/sec x sec x = 1/cos x tan x = 1/cot x cot x = 1/tan x What is sin 2x identity? sin 2x = 2sin(x)cos(x) The sin 2x identity is a double angle identity. It can be used ...
You can also get the "Reciprocal Identities", by going "through the 1"Here you can see that sin(x) = 1 / csc(x)Here is the full set:sin(x) = 1 / csc(x) cos(x) = 1 / sec(x) cot(x) = 1 / tan(x) csc(x) = 1 / sin(x) sec(x) = 1 / cos(x) tan(x) = 1 ...

Trig identities are notoriously difficult to memorize: here’s how to learn them without losing your mind. Starting from the Pythagorean Theorem and similar triangles, we can find connections between sin, cos, tan and friends (read the article on trig). Can we go deeper? Maybe we can ...
The commonly used half-angle trig identities are: {eq}\cos\frac{\theta}{2}=\pm\sqrt{\frac{\cos\theta+1}{2}}\\ \sin\frac{\theta}{2}=\pm\sqrt{\frac{1-\cos\theta}{2}}\\ \tan\frac{\theta}{2}=\frac{1-\cos\theta}{\sin\theta}=\frac{1+\cos\theta}{\sin\theta} {/eq...
